Coral-like lanthanum manganese oxides (LayMnOx) with a hierarchical structure nanosphere were successfully prepared using simple method, which presented high-efficiency catalytic performance for toluene combustion. Among them, La0.08MnOx the Mn3O4 phase exhibits superior activity, such as lower T95 value (218 °C), excellent H2O resistance, and stability. The effects of La addition on bulk surface physicochemical properties LayMnOx investigated by sorts characterization including X-ray...
Three MnO2 samples with flower (F-MnO2), rod (R-MnO2), and tube (T-MnO2) morphologies were constructed herein for catalytic toluene oxidation. T-MnO2 is superior to the other two in terms of performance water resistance stability combustion. Overall structural physicochemical properties characterized by X-ray diffraction, Raman spectroscopy, N2 adsorption–desorption, H2 temperature-programmed reduction, O2 desorption, photoelectron desorption verified that exhibited larger specific surface...
The instability of surface lattice On‐ (0<n<2) in the charged LiCoO₂ (LCO) limits its long‐term cycling stability beyond 4.55 V vs. Li/Li⁺. Herein, spinel and rock‐salt (RS) phases are constructed on LCO to stabilize On‐, namely S‐LCO R‐LCO, respectively. Upon at 4.6 V, loss leads a progressive deterioration phase, which ultimately transfers strong Li+‐blocking phase. In contrast, for RS phase retains stable cycles. Theoretical calculations reveal that migration barriers significantly...
To address the issues of cumulative plastic deformation and low-cycle fatigue cracking in ultra-high voltage (UHV) disc spring hydraulic circuit breakers under long-term cyclic high-pressure loads, which lead to internal structural changes affect closing time stability phase-controlled accuracy, this paper proposes a prediction model considering operating mechanism. First, Simulink-based simulation 550 kV mechanism transmission system was developed analyze influence parameter variations on...
The formation of K–O–Mn bond weaken the Mn–O–Mn which increases oxygen species mobility leading to excellent catalytic oxidation performance over OMS-2 by introducing different amounts K.
With the increasing demand for new inorganic functional materials, more and attention is paid to rare earth ion doped luminescent materials. In this work, an Eu2+ Ba4La6O(SiO4)6 phosphor was synthesized by high temperature solid-phase method. phosphor, two Ba2+ sites could be occupied cations provide different kinds of coordination environments, resulting in broad emitting bands range 450-630 nm ultra-wide excitation 250-500 nm. The presence centers verified measuring photoluminescence...
Abstract BACKGROUND Core–shell structure Mn 2 O 3 @MnO (MnO x ) has been prepared using KMnO 4 modifying spherical assembled by nanoparticles, and applied for catalytic toluene oxidation. RESULTS The MnO sample calcined at 350 °C ‐1) exhibited much higher activity compared with ‐2 (calcined 450 °C), good stability recyclability. Bulk structure, redox ability surface properties were characterized various techniques. relationship between the oxygen species of these catalysts is discussed in...
In this paper, we investigate the quasi-two-body decays $B_c \to K_0^{*}(1430,1950) D_{(s)} K \pi D_{(s)}$ within perterbative QCD (PQCD) framework. The S-wave two-meson distribution amplitudes (DAs) are introduced to describe final state interactions of $K\pi$ pair, which involve time-like form factors and Gegenbauer polynomials. calculations, adopt two kinds parameterization schemes factors: One is relativistic Breit-Wigner (RBW) formula, usually more siutable for narrow resonances, other...
